Young activists fess up to series of hacker attacks.

Ryan Ackroyd, a 26-year-old from South Yorkshire, pleaded guilty to a single count of a computer-related hacking charge, according to a report in U.K.'s The Guardian newspaper. Ackroyd admitted in court to being involved with hactivist organization Lulz Security, otherwise known as LulzSec, and to plotting a series of attacks on websites such as 20th Century Fox, Sony, Nintendo, News International, Arizona state police in the U.S., and other targets.

Less than a month after it announced its disbandment, notorious hacking group LulzSec returned on Monday to strike the website of the Sun, a UK paper owned by media (and phone hacking) baron Rupert Murdoch’s News Corporation. You can read more about Lulz Security’s latest caper after the jump.
